Professional Applications & Engineering Value

This 8-32 UNC thumb screw delivers exceptional engineering value where frequent access and tool-free operation are critical. The zinc-plated steel construction provides reliable corrosion protection in manufacturing equipment, electronic enclosures, and machinery guards. The spade head design offers superior torque application without specialized tools, while the integrated flange eliminates the need for separate washers, reducing assembly time and component count. The Class 2A thread fit ensures consistent performance in coarse thread applications where rapid installation and removal are essential for maintenance panels, access doors, and adjustable components. These industrial thumb screws solve the common challenge of balancing quick disassembly needs with the structural integrity required in demanding environments.

Specification Summary & Compliance

This flanged thumb screw features precise 8-32 UNC coarse threads with Class 2A thread fit per standard inch system specifications. The fully threaded design maintains consistent engagement across the entire 3/8" length, while the 0.281" flange diameter provides enhanced bearing surface. Manufacturing complies with RoHS 3 (2015/863/EU) environmental standards, ensuring restriction of hazardous substances. The combination of Rockwell B55 hardness and 40,000 psi tensile strength validates mechanical performance for industrial fastening requirements.
